LATEST: Cardano has activated its van Rossem hard fork, cutting smart contract costs and setting the stage for its major Ouroboros Leios scalability upgrade later this year.

What happened

Cardano activated the van Rossem hard fork, which lowers the cost of running smart contracts and prepares the network for the upcoming Ouroboros Leios scalability upgrade later this year.

Confirmed

Global impact / market context

Lower smart‑contract fees make Cardano more attractive to developers and users, potentially increasing transaction volume and ecosystem growth. The upgrade promises higher throughput, which can support more complex applications and competition with other blockchains.

Analyst inference

In the broader crypto market, many platforms are cutting fees and boosting speed to win users. Cardano’s fork and planned upgrade aim to keep it competitive as investors look for blockchains that can scale efficiently.

Analyst inference

What to watch

1. Track the official rollout timeline for the Ouroboros Leios upgrade and any announced delays, as timing will determine when lower fees and higher capacity become available. Proposed
2. Watch developer activity and the number of new decentralized applications on Cardano after the fee reduction, indicating whether lower costs are attracting more projects. Proposed
3. Observe changes in transaction volume and average fee levels on Cardano, which will show if the fork’s cost cuts are translating into higher network usage. Proposed
